Upvote for: Global during night reset system for first win of the day bonus
I always thought that Warframe was the only game with a first whatever of the day bonus to get the system right. It always felt bad that I never was able to get the first win of the day bonus when playing earlier in the day, than when i got it the prievious day. It's almost like the game wants you to structure your day around it if you want the bonus.
The way it works in Warframe is that the system resets somewhen during the night time depending on which server you are plying on and not 24 (think it's 22 for League) hours since you got the last bonus. That ensures you always get the bonus if it's the first time of you playing that day independent from when you got it the last day.
As it can only see positive aspects of a system like that an no way to get the bonus more than once a day it would be what I'd whish for in League.
